“…Polymers consisting of lone pair electrons subgroups such as carbonyl (C═O), amino (─NH 2 ), carboxyl (─COOH), or/and hydroxyl (─OH), are generally good can-didates. In the past decade, researchers have explored various polymer-based RTP systems based on different polymer matrices, including PLA, [20,33] polyacrylamide (PAM), [18,39] poly(vinyl alcohol) (PVA), [40,41] and some biogenic polymers that are available from nature, [16,42] like sodium alginate (SA). [16] Based on the composition, polymer-based RTP materials can be broadly classified into three categories: i) nondoped phosphorescence polymers where aromatic chromophores and polymers are chemically bonded, ii) doped phosphorescence polymers where aromatic chromophores are encapsulated into polymers via weak interactions, and iii) clustering-triggered emission (CTE)-based phosphorescence polymers, which refer to nonconventional polymers with nonconjugated structures based on electron-rich units.…”

Organic room‐temperature phosphorescence (RTP) materials are actively explored as attractive candidates for optoelectronic and bioelectronics applications given their unique long‐lived excited‐state features and inherent merits of low‐cost, appreciable functionality, and good biocompatibility. In recent years, many efforts in molecular design and aggregation modulation are devoted to achiev efficient RTP from organics, among which an emerging strategy focuses on confining chromophores within polymer matrices. Polymers possess intertwined chains making them a good platform to restrain the nonradiative decays and quenching, allowing the triplet excitons to survive a long time enough for emission at room temperature. Progress relating to polymer‐based organic RTP materials is highlighted as a new creative subject in the field. This review outlines recent advancements in polymer‐based organic RTP materials. The fundamental mechanism of organic RTP is first presented. Thereafter, design considerations and strategies to construct polymer‐based organic RTP materials are summarized in detail. Several promising progresses in the proposed use of these RTP materials, such as encryption and anti‐counterfeiting, sensors, and bioimaging are overviewed. Finally, the challenges and future perspectives are discussed to emphasize the directions that deserve focus attention in the field.

“…Aerogel, a type of porous solid material featuring extremely low density, low thermal conductivity, high porosity, and large specic surface area (SSA), has attracted increasing attention from both academia and industry, not only because of its exceptional properties but also due to numerous components that can be fabricated into the aerogel. [1][2][3][4] To name a few, inorganic oxides (such as SiO 2 , Al 2 O 3 , ZrO 2 , and TiO 2 ), [5][6][7][8][9][10] metals (such as Ag and Au), [11][12][13] carbon (carbon nanotube and graphene oxide), [14][15][16] polymers (such as polyimide, cyclodextrin, polyvinyl alcohol, and Kevlar), [17][18][19][20] and natural products (such as cellulose, wood, and chitosan) [21][22][23][24][25] have been used to synthesize aerogels with resistance to extremely low temperature and ultrahigh temperature. 26,27 Thus, aerogels nd wide applications in the eld of thermal insulation, 28,29 environment, 30,31 aerospace, 32 catalysts, 33,34 energy, 35 and biomedicine.…”
